  • 3. 3 1.Introduction 1.1. The Wood Cement Composite. WCC The raw material from which the Anti-blast products are composed is wood cement composite, which consists of mineralized wood chips with homogeneous texture bonded with Portland cement. The mineralizing treatment, maintains intact the mechanical properties of the timber holding the biological degradation processes, making the timber practically inert material with a large fire resistance. The chips coated with Portland cement forms a stable structure, compact, strong and durable, while its honeycomb structure provides good thermal performance, lightness and gives a material with high absorption capacity of the pressure waves. The material is resistant to water, ice and moisture, is breathable and safe, meeting all the principles of green building. The material does not contain any toxic materials, produces no harmful gases, is not radioactive or flammable. Their physical characteristics as perspiration, the absence of electrostatic charges, the ability to retain heat and moisture regulating ownership, guarantees optimal conditions of habitability. Wood cement conglomerate has unlimited durability, and is not subject to chemical or biological degradation. For all these reasons the wood cement conglomerate is regarded as an environmentally friendly material.
  • 4. 4 2.The construction system Anti-blast is a system of construction of solid walls with reinforced concrete formwork, whose structure absorbs more energy on impact than a conventional concrete wall. Anti-blast block is an integrated construction system, which allows to build the walls, the floor and roof of a building. The system involves the construction of:  Insulated concrete walls. Using a formwork block cement conglomerate wood material of very high thermal insulation and sound absorption, whose function is to coat the wall. The system allows rapid implementation and dry. The concrete core of the wall, provides high thermal inertia, reaching the comfort of old stone or adobe houses, which kept the heat in winter and cool in summer. The walls alveoli allow breathable enclosure of the housing, quickly evacuating the humidity from inside to outside (water vapor migration). The walls have extreme structural strength and, with a proper calculation of the veil reinforced concrete, can obtain buildings resistant to earthquakes and explosions. The wall reaches very high values of acoustic insulation, since a partition 45 dB, 52 dB in the wall of 20 cm thickness, up to 60 dB of the wall of 30 cm.  Insulating floors and roofs, based on the use of self-supporting sheets of Wood Cement Composite, quick start that give the forged piece or cover of a high thermal and acoustic insulation. The properties are similar to those of the walls.  Noise barriers and protection, with high acoustic power and quick and easy placing. Particularly suitable in the protection of explosion due to its high absorption capacity and strength. 2.1. Security applications Anti-blast system prevents buildings from collapse in case of explosion or earthquake, and in turn the CMC double layer absorbs the energy of the shock wave propagation mitigating and avoiding fragmentation of the wall (spalling). The system allows the reinforcement of new or old buildings, providing a solid concrete structure for the building, which ensures strength front to gas explosions, bombings, earthquakes or hurricanes. The composition of the cement particle board (WCC) absorbs energy from the shock waves, causing minor damages to the structural integrity and preventing spalling. The system is highly recommended for: • Barracks (Police, Army…) • Bunkers and Panic Rooms. • Border Checkpoints, Watchtowers... • Hazardous Buildings (Stores, Boiler Rooms,...) • Military Residential Buildings and Public Security Offices • Perimeter Security Fences • Fuel Tanks • Storage of Ammunition and Explosives The problem of Security in construction requires strength against the impact of an explosive, projectiles and debris, preventing detachment of the inside construction. The WCC absorbs coating around the core, Anti-blast removes kindling, while attenuates shock waves after an explosion.
  • 5. 5 2.2. Anti-blast behavior The problem of construction security requires strength against the impact of an explosive device, avoiding projectiles and debris shedding that act as shrapnel into the building. This detachment occurs when cracks are wider than 5 mm. In a conventional reinforced concrete wall, before an explosion there is no attenuation, so that the shock wave transmitted to the opposite face produces concrete breaking, parting out shrapnel that is very dangerous for people are behind the wall. On the Anti-blast wall, features a double absorbent lining attenuates shock wave and the transmitted waves, mitigating the effects due to the explosion, and reducing the possibility of collapse on the concrete. Additionally, concrete is confined within two more flexible and absorbent layers, so in case of cracking and peeling of rubble these are confined within the wall.
  • 6. 6 2.3. Additional advantages 2.3.1. Thermal Insulation The low thermal conductivity of the wood cement composite (0.11 W/mºK) and polystyrene (0.04 W/mºK) allows achieving a high thermal insulation capacity. Furthermore, the absence of mortar in the joints of the blocks avoids the thermal bridge, improving the insulation values. 2.3.2. Acoustic Insulation Wood cement composite is highly absorbent, and the high mass of the concrete wall can achieve excellent sound insulation values. 2.3.3. Thermal Inertia The wall of a single sheet of WCC achieves excellent thermal insulation value, around 12 hours lag and 90 % damping, which results in an excellent thermal inertia. This way you get a good performance of the walls, in winter with high thermal insulation, and in summer, where the thermal stability achieved is much higher than the usual multilayer walls. 2.3.4. Sustainability The system allows a "Breathing" active through the wall, the migration of water vapor by transverse walls Support alkali prevents the growth of mold and mildew associated with allergic diseases, improving the habitability of the interior areas.
  • 7. 7 3.Ballistic test AP14.5 mm against walls of 25/30 cm thickness In ballistic tests made in a concrete wall of 30 cm thickness, and another 25 cm thickness wall of reinforced concrete, it’s shown as in the wall of concrete there is spalling in the other side of the impact when an artillery projectile 14.5 mm. hits the wall. Performing the same test in an Anti-blast wall of 30 cm thickness, we can see that in the opposite face does not occur any fracture or spalling. Inner face with fractures and flying debris in a concrete wall of 25 cm thickness, after the hit of a 14.5 mm projectile Inner face of a wall Anti-blast of 30 cm thickness, no broken after the hit of a 14.5 mm projectile
